WILLIAM BARTHOLOMEW, OF CHICAGO, ILLINOIS, ASSIGNOR TO TROY LAUNDRY IIIACHINERY COMPANY, LTD., A CORPORATION OF NEW YORK.

CYLINDER WASHING-MACHINE.

LLSLSEMM Specification of Letters Patent.

Application filed December 2, 1912. Serial No. 734,541.

To all whom it may concern:

Be it known that 1, WILLIAM BAn'rnoLo- MEW, a citizen of the United States, reslding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cylinder Washing- Machines, of which the followlng 1s a spec1 fication.

My invention relates in general to laundry machinery, and more particularly to cylinder washing machines.

In the use of cylinder washing machines the clothes or other articles to be washed are placed in the cylinder which is then re volved within the inclosing tank which contains the suds in the bottom thereof. It is necessary that all portions of the artlcles should be subjected to the suds 1n order that they may be thoroughly cleansed. To accomplish this it is desirable that as the cylinder revolves through the suds in the bottom of the tank, the suds should be forced through the cylinder into contact with the articles, and also that the suds should be carried upwardly by the surface of the cylinder so as to flow downwardly through the cylinder upon the articles therein. The articles are therefore not only subjected to the suds forced through the lower portions of the cylinder as it passes through the suds, but also to the suds falling upon them from the upper surface of the cylinder. It is further desirable that the foregoing actions should occur when the cylinder is rotated in either direction so that all portions of the articles may be the more thoroughly exposed to the suds.

The primary object of my invention is to provide a cylinder for washing machines in which the articles will be thoroughly subjected to the action of the suds, not only by effectively forcing the suds through the portion of the cylinder passing through the suds, but by scooping the suds up and carrying them to a point above the articles so that they will fall upon them within the cylinder.

A further object of my invention is to provide/a cylinder for washing ,machines in which the inclosed articles will be thoroughl-y subjected to the action of the suds without danger of injury to the articles, and which will be simple in construction and durable in use. f

My invention will be more fully disclosed hereinafter with reference to. the accom-,

- away; and Fig. 2, a transverse sectional view through the lower portion of the cylinder shown in Fig. 1.

The same reference characters willbe used to designate the same parts in the two figures of the drawing.

Reference character A indicates one of a number of staves forming the cylindrical. wall of the cylinder of a washing machine. The ends of the staves A are secured around the peripheries of the two cylinder heads B, B. The ends of the staves may be securely connected with the peripheries of the cylinder heads in any suitable manner, as by hoops b, b, which surround the ends of the staves and clamp them tightly to the cylinder heads.

Intermediate of a plurality of staves are located longitudinal bars C which serve to rigidly connect the cylinder heads 13' so as to impart to the cylinder the requisite structural strength. The bars C project inwardly from the inner surface of the staves A so as to form ribs which serve to carry the wet articles with the cylinder as it rotates a distance above the bottom of the cylinder so that the articles will fall back by gravity and thereby be turned over and thoroughly exposed to the suds.

D, D designate trunnions projecting axially outwardly from the cylinder heads B which are adapted to engage hearings in the ends of the tank for rotatably supporting the cylinder. As neither the manner of supporting the cylinder nor the construction of the inclosing tank form parts of my present invention, they need not be disclosed. Fixed to one of the trunnions is any suitable means for communicating rotary motion to the cylinder, such for instance as a gear E, which is adapted to be driven by any suitable power connections.

Several of the staves A are connected to strap hinges F and F so as to form an outwardly swinging door to permit access to the interior of the cylinder for the insertion and removal of the articles.

f and f designate any suitable fastening devices for retaining the cover in closed position and for permitting the cover to be opened. Preferably the stave at the free end of the door. upon which the latches are mounted is made imperforate so as to possess greater structural strength. My invention consists essentially in the structure of the staves A and in their relation to each other. It will be observed that each stave A is provided on its outer surface with inwardly inclined portions A and A which terminate adjacent outwardly projecting shoulders a and a Spaced holes a are formed through the inclined portions of each stave adjacent the respective longitudinal shoulders d and (E.

The adjacent staves are reversed with respect to the inclination of the inclined portions of their outer surfaces, as clearly shown I in Fig. 2. By the use of this alternate arrangement of the staves the operation of the cylinder will be the same when rotated in opposite directions.

The operation of my improved cylinder washing machines is as follows: When the cylinder is rotated in either direction the shoulders a and a on alternate staves serve to direct the suds through the openings at extending through the inclined portions of the outer surface of such staves adjacent theabrupt radial surfaces of the shoulders.

The suds are therefore forced through the staves throughout the portion of the cylinder which passes through the suds. The longitudinal peripheral grooves formed on the outer surfaces of the staves by the inwardly inclined portions and the adjacent shoulders, serve to carry the suds upwardly with the cylinder to a point above the clothes at which the suds flow through the holes and fall upon the articles in the cylinder. The rotation of my improved cylinder therefore serves, through the inwardly projecting bars C, to roll the articles around by carrying them upwardly until they fall downwardly bvgravity, and thereby exposes all portions of the articles to the suds forced through the portion of the tank passing below the level of the suds and also through the suds which are carried upwardly and then fall through the cvlinder upon the articles.

From the foregoing description it will be observed that in my improved cylinder washing machines the articles will be thoroughly agitated and efiiciently subjected to the action of the suds without in any wise injuring the articles during such treatment.

I claim:

1. In a device of the character described, the combination with cylinder heads, of a plurality of wooden staves forming a cylindrical wall, each of said staves comprising a longitudinal inwardly inclined outer surface and a radial longitudinal shoulder projecting outwardly from the inner edge of said inclined surface, a plurality of spaced holes being formed through the inclined surface adjacent said shoulder, and means for securing said staves to the cylinder heads in alternate arrangement.

2. Ina device of the character described, the combination with cylinder heads, of a plurality of staves forming a cylindrical wall, each of said staves comprising a plu rality of longitudinal inwardly inclined surfaces on its exterior and a radial longitudinal shoulder projecting outwardly from the lower edge of each of said inclined surfaces, a plurality of spaced holes being formed through the inclined surfaces adjacent the shoulders, and means for securing said staves: to the cylinder heads in alternate arrangement.

3. In a cylinder for washing machines, the combination with cylinder heads, of

spaced longitudinal bars connecting saidheads, a plurality of staves intermediateof said bars and connected to said heads, each of said staves comprising a longitudinal inwardly inclined portion on its outer surface and a radial longitudinal shoulder projecting outwardly from the lower edge of said inclined portion,holes being formed through each stave adjacent each of said shoulders, and means for securing said staves to the cylinder heads with inclined surfaces on adjacent staves extending in opposite directions.

In testimony whereof, I have subscribed my name.

WILLIAM BARTHO LOMEW.
